Method and system for transmitting downlink control information to user equipment (UE)

Abstract

Embodiments herein provide a method for transmitting downlink control information to a User Equipment (UE) in a wireless communication system. The method includes segmenting a plurality of Aggregation Levels (ALs) across multiple bandwidth parts (BWPs) in a Physical Downlink Control Channel (PDCCH). Further, the method includes transmitting the plurality of segmented aggregation levels across multiple BWPs to one or more UEs. The segmented plurality of ALs comprises multiple combinations of ALs across multiple BWPs. The proposed method includes narrowing down the search space by signaling to the UE explicitly or implicitly the AL resources that the UE has to monitor to perform the decoding of the PDCCH. In some embodiments, the length of the control information formats is modified such that the UE needs to perform a minimum number of blind decoding attempts.

AI Technical Summary

Benefits of technology

The patent text describes a wireless communication system, particularly a method for transmitting control information to a user equipment (UE) in a 5G network. The technical effect of this patent is to provide a more efficient and effective way of transmitting control information to UEs in a wireless communication system, particularly in a 5G network. The method takes into account the characteristics of the system and the needs of the UEs, and ensures that the control information is transmitted in a way that optimizes the use of network resources and improves the efficiency of the communication. This is important for providing effective and reliable services to users in a wireless communication system.

Problems solved by technology

The result of the analysis shows that an average UE spends a significant amount of time performing a blind decoding of the PDCCH leading to unnecessary power consumption.
